The difference between two negative numbers is negative if the second number ( the number you are subtracting from the first) is less in value than the first. For example (-3) - ( -2) = -3 + 2 = -1 (-3) - (-4) = -3 + 4 = + 1
Negative times negative equals positive. Positive times positive equals positive. Positive times negative equals negative. If you have more than two numbers, multiply the first two and then apply these rules to each successive number in turn.

Negative rational numbers are used in the same way that negative whole numbers are used: they are simply the additive inverses of their positive counterparts.
The concept of negative numbers was first documented by Chinese mathematicians around the 2nd century BC. These numbers were initially used to solve practical problems related to debt and payments.
Exponents are negative numbers. This is used in math a lot.
Negative numbers were first recorded in ancient China, where they appeared in the Han Dynasty around the 2nd century BCE, primarily in the context of accounting and mathematics. The Chinese used red rods for positive numbers and black rods for negative ones. While other cultures, such as Indian mathematicians, also recognized negative numbers later on, it is China that is credited with their earliest documented use.
